[asterisk-ss7] dpc and adjpc

[Eric Huang 黃富鴻]

Hi Matthew and all ,
I am still trying to find the problem about SS7 signaling route. Now I
am using SS7 protocol analyzer to check further my problem.
my scenario:

Signaling (16):
Asterisk (PC 100) <-> MGW (PC 1001) <-> MSS (PC 1000)

Circuit (1-15, 17,31):
Asterisk (PC 100) <-> MSS (PC 1000)

Asterisk's config in zapata.conf:
pointcode = 100
adjpointcode = 1001
defaultdpc = 1000

MSS and MGW have configured routing correctly to see Asterisk (PC
100). I have seen STLM between PC 100 and PC 1000, but CGR from PC 100
to PC 1001 have no response back. I guess it's some problem with
routing. I am in the stage to link up MTP3 between PC 1000 and PC 100.
No successful ISUP messages yet in my scenario. Because I am really
new to SS7, hard for me now to describe/identify the problem.

Can you describe a typical flow for both MTP3 and ISUP layers? Any
suggestions to me to identify my problem? thanks for help!

cheers,
/eric
